None of the continental forms are in the collection, and therefore their relationship to each other and to the West Indian species cannot be here given. They are: (1) _Q. lugubris_, SWAINS. (Cabinet Cyclopædia, p. 299, 1838.—CASS. Pr. A. N. S. 1866, 408). _Hab._ S. Am., Trinidad. (2) _Q. mexicanus_, CASS. (Pr. A. N. S. 1866, 408). _Hab._ Mexico. Besides these are the two following, whose habitats are unknown: _Q. inflexirostris_, SWAINS. (Cab. Cyc. p. 300, 1838), and _Q. rectirostris_, CASS. (Pr. A. N. S. 1866, 409).

Cyc. 1838, 354, of Peru, are not in the collection; they are probably referrible to the _major_ type. Quiscalus purpureus, BARTR. THE CROW BLACKBIRD. [Illustration: Quiscalus purpureus.]
